Predation is another mechanism in which species interact with each other. Predation is when a predator organism feeds on another living organism or organisms, known as prey. The predator always lowers the prey's fitness. Also, a predator is an organism that eats another organism. The prey is the organism which the predator eats. Some examples of predator and prey are lion and zebra, bear and fish, and fox and rabbit.
Answer:
During the oxidation of glucose in the liver the malate aspartate shuttle system is used, therefore, two additional ATPs get generated at the step constituting glyceraldehyde-3-phosphate dehydrogenase.
On the other hand, in the brain, a cell uses the glycerol phosphate shuttle system, which generates two less number of ATPs. However, the remaining of the energetics for the number of ATP in both cases are similar.
Thus, the difference is based upon the kind of shuttle system used that leads to the production of 32 ATPs in liver cells and 30 ATPs in the brain cells.
Answer:
Birds and bats have homologous limbs because they are both ultimately derived from terrestrial tetrapods, but their flight mechanisms are only analogous, so their wings are examples of functional convergence.
